する、引いては信頼性の減少につながる。However, when such a female-to-female terminal 5 is used in the plate fuse device 1, the terminal portion of the plate fuse device is also made of fuse alloy and is soft, so it may be damaged when inserting the plate fuse device (see Figure 4 a). ■During use, the plate fuse terminal part becomes hollow due to creep (see Figure 4), which reduces the contact pressure, which in turn leads to a decrease in reliability.
なお・第４図中７はエツジ、４はくぼみを示している。Note that in Fig. 4, 7 indicates an edge and 4 indicates a recess.
本考案は上記欠点を解消するため案出されたものである
。The present invention has been devised to eliminate the above-mentioned drawbacks.
以下本考案を図面と共に説明する。第５図に於いて２１

３図に示したような２個の弾性的断面弧状板部２７が背
板部２５左右両側から出ている。(Hereinafter, the above will be abbreviated as a single spring type for convenience.) The terminal connection side of the bus bar, that is, the end opposite to the side where the flat plate part 21 and the flat plate part 23 of the back plate part 25 are located is shown in FIG. Two elastic cross-section arc-shaped plate portions 27 protrude from both left and right sides of the back plate portion 25.
第６図に示す様に上記弾性的断面弧状板部２７と背板部
２５の間には間隙２８を有してバスバー１１の端子部１
４を弾性的に挟持接触せしめるようになっている。As shown in FIG. 6, there is a gap 28 between the elastic arc-shaped plate part 27 and the back plate part 25, and the terminal part 1 of the bus bar 11
4 are brought into elastic pinching contact.
（以後上記を便宜上ファストンタイプと略記する。(Hereinafter, the above will be abbreviated as Faston type for convenience.
）以上の様な本考案によると、下記の様な利点がある。) According to the present invention as described above, there are the following advantages.
■ 板フユーズの端子部に接触するめす−めす端子の接
触面はフラットである。■ The contact surface of the female-to-female terminal that contacts the terminal part of the plate fuse is flat.
従って前記傷、くぼみの発生を防止し併せて熱放散をよ
くしフユーズ性能の低下を防ぐ、
■ バスバーの端子部に接触する側はファストンタイプ
を用いている。Therefore, the above-mentioned scratches and dents can be prevented from occurring, and heat dissipation can be improved to prevent deterioration of fuse performance.
従って小さい形状で大きな接触力が得られる（片ばねタ
イプで大きな接触力を得ようとすれば形状が大きくなる
）。Therefore, a large contact force can be obtained with a small shape (if you try to obtain a large contact force with a single spring type, the shape will have to be large).
即ち板フユーズの端子部側では前記第４図で述べた欠点
を解消するため弱い接触力を用い、それを錫めっきを施
すことにより補っているが、バスバーの端子部では十分
強く接触させるのでめっきが不要でコスト低減になる。That is, on the terminal side of the plate fuse, a weak contact force is used to eliminate the drawback described in Fig. 4, and this is compensated for by applying tin plating, but on the terminal side of the bus bar, the contact is strong enough, so plating is applied. is not required, reducing costs.
